Not if you update the content. When reading up on interfaces that change rapidly, I'll often throw $CURRENT_YEAR into the search bar. If your post has been updated with current content, I'd like it to be included in my results.

It depends on the content and the type of updates you make.

As long as I do a significant update to an article, and make sure it's generally up to date and still entirely relevant, then I'll update the date to match.

When people look at the dates (in SERP) they generally want to know if the article is still relevant or if they are likely to find outdated information there. At least that's how I think.

Automatically updating dates without actually revising the content on the other hand... That's not something I'd want to endorse.
